Stage 2.6A — Readiness Guard v3

2 min read Revision 1

05 — Readiness Guard v3 (SUPERTRACK E)

Readiness now consumes the registries and cannot false-green from literals. It stays BLOCKED.

Objects

  • v_qt001_apply_readiness_guard_v3 — one row per gate (gate, gate_class SSOT/APPLY, ready, detail).
  • v_qt001_apply_readiness_dashboard_v3 — rollup + apply_gate label.
  • v_qt001_readiness_v3_no_go_guard — pass = readiness is correctly blocked.

Gates and live state

gate class ready
plan_registry_current SSOT true
hardcode_eliminated_or_classified SSOT true
tier_registry_present SSOT true
signoff_registry_present SSOT true
tier_permits_apply APPLY false
independent_signoff_safe APPLY false
owner_execute_permit_valid APPLY false
ledger_contract_present APPLY true
writer_enforcement_wired APPLY false
scale_safe APPLY false

Result

SSOT gates green 4/4; APPLY gates green 1/6 (only the existing ledger contract); overall_ready = false; apply_gate = BLOCKED_STAGE2.6A_SSOT_ONLY_PENDING_NEXT_LAYERS_AND_REAUDIT; blocking_gates = independent_signoff_safe, owner_execute_permit_valid, scale_safe, tier_permits_apply, writer_enforcement_wired.

Why it cannot false-green

Each APPLY gate is computed from registry data: tier_permits_apply reads qt001_tier_registry.apply_allowed (all false), independent_signoff_safe reads the signoff registry (NOT_SAFE), owner_execute_permit_valid counts open execute permits (0), scale_safe reads v_qt001_scale_not_safe_guard (scale_not_safe true), writer_enforcement_wired reads the writer contract's enforced_in_writer flags (all false). There is no literal that can flip readiness to ready; only governed data changes plus a fresh re-audit can.

Relationship to v2

The pre-existing v_qt001_apply_readiness_dashboard_v2 (with HC-02's literal false) is retained but is no longer the authority dashboard. v3 is the SSOT-consuming readiness surface.
